Moore is an intellectual tour de force. In this book he attempts to explain how democracy developed in some states, while other, seemingly similar, states turned to fascism and authoritarianism. While I certainly cannot cogently summarize Moore in a small paragraph, it remains a book and an argument that needs dissemination. In general, the key to understanding how states develop is to understand the balance of class power within each society. The choice of regime, or rather the regime type that develops within a state, is determined by the dominant class and with whom that class aligns. According to Moore democracy develops if the bourgeoisie gains enough power to break the hold of the aristocracy and the failure to do so can not only doom democracy, but it also raises the possibility of fascism. Moore supplements his theoretical augments with an ample amount of well-analyzed historical case studies. In the end, even if one does not agree with his arguments or conclusions, the book still needs to be read, understood, and engaged by anyone who wants to understand democratization.
